If you want to change the ui-elemnts of your application, then you can customize the main.xml

<TextView
  android:id="@+id/text_view2"
  android:text="Font size 25dp or dip (Density-independent-Pixels)"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:textColor="#FF0000"
  android:textSize="25dp"
  />

Code is taken from this link https://android--examples.blogspot.se/2015/01/textview-font-size-in-android.html

Howevver, If you want to update the ui at runtime, then you most send a request to the ui. Check this thread Updating Android UI using threads Both Franco and user634618 have pretty good answers regarding this.
